AI总结:

本文证明曲面悬挂半流在屋顶函数 Lipschitz 且非局部常上同调时关于 SRB 测度拉伸指数混合,并推广至双曲斜积、吸引子及余维一拓扑混合 Anosov 流。

摘要:

对于作为 \(C^{1+α}\) 扩张 Markov 区间映射的悬挂的曲面半流,我们证明:在屋顶函数 Lipschitz 连续且不与局部常函数上同调的假设下,该半流关于 SRB 测度呈现拉伸指数混合。此结果推广到双曲斜积半流和双曲吸引子。具体而言,具有 Lipschitz 连续稳定叶层的余维一拓扑混合 Anosov 流关于其 SRB 测度表现出拉伸指数混合。

英文摘要:

For a surface semiflow that is a suspension of a \( C^{1+α} \) expanding Markov interval map, we prove that, under the assumptions that the roof function is Lipschitz continuous and not cohomologous to a locally constant function, the semiflow exhibits stretched-exponential mixing with respect to the SRB measure. This result extends to hyperbolic skew-product semiflows and hyperbolic attractors. Specifically, codimension-one topologically mixing Anosov flows with Lipschitz continuous stable foliations demonstrate stretched-exponential mixing with respect to their SRB measures.
